INVENTOR. /7 Ford? ALLENBACH Patented Jan. 3, 1950 UNITED STATESPATENT OFFICE MUSIC SHEET TURNER Roy Earl Allenbach, Pueblo, 0010. Application August 6, 1949, Serial No. 109,009 Claims. (01. 84-489) This invention relates to a sheet music turner, and has for its principal object the provision of a simple, unitary device which can be readily mounted on a music stand or upon the music rack of an organ or other instrument, and which will turn the center sheet usually found in conventional sheet music by a simple flip of the finger so as to avoid the confusion and interruption occasioned by turning the music while play- Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efficiency. These will become more apparent from the following description.

In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.

In the drawing:

Fig. 1 is a perspective view, illustrating the improved sheet music turner as it would appear in use;

Fig. 2 is a longitudinal section therethrough, taken on the line 2-2, Fig. 1;

Fig. 3 is a detail face view of a sheet reinforcement member employed in the improved music turner;

Fig. 4 is an end view of the music turner; and

Fig. 5 is an enlarged, detail, perspective view of the turning shaft employed in the invention.

In Fig. 1 the cover of a typical piece of sheet music is indicated at H], and the middle sheet thereof is illustrated at H. designed to turn the middle sheet H back and forth within the cover [0.

The sheet music is supported on a sheet metal backing plate 12, the lower edge of which is turned forwardly to form a shelf portion l3, thence downwardly and rearwardly to form a channel-like housing M which is open at the rear.

The music is turned by means of a winding shaft I5 which is rotatably mounted in a bracket plate 26 positioned above the bottom of the housing M. The winding shaft extends upwardly through the shelf plate [3 and terminates in a square socket member 16 at its upper extremity. The shaft l5 and its socket it are inclined rearwardly parallel to the plane of the backing plate l2.

The shaft I5 is rotated back and forth by means of an actuating lever 11 which projects through a lever opening is in the front of the The invention is housing [4. The lever H is mounted on a pivot pin I9 extending between the shelf l3 and a sec- ,ond bracket plate 21.

A flexible cord 2c extends from the lever member l'l forwardly of the pin l9 and about the shaft J5 and through cord openings 28 in the latter.

The cord 20 terminates in a tension spring 2| which is secured to the extremity of the lever member I? rearwardly of the pivot pin 19.

An L-shaped sheet-binding member 22 is cemented or otherwise secured along the inside vertical edge of the inner sheet H and along the bottom edge thereof, as shown in Fig. 1. The binding member 22 is preferably formed of transparent plastic and is slotted, as shown at 23, to form a downwardly-extending mounting tongue 24.

In use, the cover IE] is placed against the backing plate I2. The lever I1 is swung to the left, and the mounting tongue 24 is inserted in the socket It. The open back of the housing [4 is slipped over a music stand or shelf, the latter entering below the bracket plates 26 and 21 and above the bottom of the housing M. on a piano or organ or similar instrument, the entire device is simply rested on the music shelf thereof.

When the musician has reached the end of the first page, he swings the lever ['1 to the right. This causes the tension spring 21 to stretch and. pull on the cord 26 so as to rotate the shaft l5 and swing the sheet of music to the left. This sheet is returned by simply swinging the lever in the opposite direction.

The music can be instantly lifted from the shelf, since the tongue 24 is not secured in the socket 16. It is preferred to form two protuberances 25 in the shelf at each side of the shaft 5 to prevent the cover In from swinging forwardly to follow the sheet H.

While a specific form of the improvement has been described and illustrated herein, it is to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent is:

1. A sheet-turning music rack comprising: a backing plate adapted to support the cover sheet of music; an L-shaped binding strip adapted to be secured along the inner and bottom edges of a middle sheet of music; a shelf projecting forwardly from said backing plate to support said sheets; a shaft extending upwardly from said shelf forwardly of the middle portion of said backing plate and parallel to the latter; means on said shaft engaging said binding strip; and means for rotating said shaft.

2. A sheet-turning music rack comprising: a backing plate adapted to support the cover sheet of music; an L-shaped binding strip adapted to be secured along the inner and bottom edges of a middle sheet of music; a shelf projecting forwardly from said backing plate to support said sheets; a shaft, extending upwardly from said shelf forwardly of' the middle portion of said backing plate and parallel to the latter; means on said shaft engaging said binding strip; mounted on and below said shelf and projecting forwardly therefrom at one side of said shaft; a pivot member supporting said lever from said shelf; and a flexible medium extending around said shaft and being secured at. its extremitiesto said lever member at opposite sides of said pivot, member so that when said lever member is swung from side to side, said shaft will be rotated back andlforth;

3; A sheet-turning music r-ack comprising: a backing plate adapted to support the cover sheet of music; an L-shaped binding strip adapted to be I secured along the innerand bottom edges of a middlesheetof: music; ashelf projecting forwardly from said backing plate to support said a shaft extending upwardly from said shelf forwardly of the middle portion of said backing plate and parallel to the latter; a noncircular tongue extending downwardly from said bindingstrip; a non-circular socket carried on the uppersextremity of said shaft and adapted to receive said tongue; and means for rotating said shaft.

4; A sheet-turning music rack comprising: a, backing plate adapted to support the cover sheet of music; an L-shaped binding strip adapted to be secured along the inner and bottom edges of a middle sheet of music; a shelf projecting fora lever;

wardly from said backing plate to support said sheets;

shelf backing plate and parallel to the latter; a noncircular tongue extending downwardly from said binding strip; a non-circular socket carried on the upper extremity of said shaft and adapted to receive said tongue; a flexible member wound aboutsaid, shaft below. said shelf; a lever; and a pivot member securing-said. leverbelow said shelf so that it will project forwardly therefrom, said flexible member being connected with said lever at opposite sides of said pivot member so that when said lever-is oscillated back and forth, said shaft will be rotated.

5. A sheet-turning music rack comprising: a backing plate-adapted to support the cover sheet of music; an L-shaped binding strip adapted to be secured along the inner and bottom edges of a middle sheet of music; a shelf projecting forwardly from saidbacking; plate to support said sheets; a shaft extending upwardly from said shelf forwardly of the middle portion of said backing plate and parallel to the latter; a noncircular tongue extendingdownwardly from said binding strip; anon-circular socket carried on the upper extremity of said-shaft and adapted to receive said tongue;- a flexible member wound aboutsaid shaft below-saidshelf; a lever; a pivot member securing said lever below said shelf so that it will project forwardly therefrom, said flexible, member being' connected with, said lever at opposite sides of said pivot member so that when said 1ever-is oscillated back and forth, said shaft will be rotated; and a ten-s-ionspring interposed in said fiexible member for maintaining the lattertaut:
